Title: Wavelength-tunable source of pulsed laser radiation for vis-nir spectroscopy
Inventor: ANTANAVIČIUS ROMALDAS
IPC: H01S3/00
Filed: 2020-12-02
Abstract: The invention relates to laser sources with continuously tunable wavelength and narrow bandwidth. The source for visible and near-infrared spectroscopy consists of a pump pulse source forming bursts of picosecond pulses of high pulse repetition rate, and a synchronously pumped optical parametric oscillator. The pump source comprises a solid-state regenerative amplifier having one or two electro-optical switches inside its resonator. The switches create partial transmission of the resonator for a time interval longer than a resonator roundtrip time, and couple out a part of energy of a pulse circulating inside. Bursts of (5–10) ns duration are formed, which are filled with high peak power picosecond pulses. Pulse repetition rate of the order of GHz of pump pulses allows the construction of a compact optical parametric oscillator. The whole set of parameters ensures high energy efficiency, stability and an ability to generate output pulse bursts repeating up to 10kHz repetition rate. When pumped with near-infrared laser radiation or its harmonics, the wavelength tuning range covers the visible and near-infrared spectral regions.

Patent MX-174401-B (MX)
Inventor: WEIK HARTMUT
IPC: H04L12/70
Filed: 1988-12-14
Abstract: In high-speed packet switching, packets of specific connections (CS1, CS2), e.g. speech, moving image, are to be handled with higher priority than packets of other connections (PS1, PS2, PS3), e.g. data, without delay jitter and without losses. 
<??>In a known method, a division is made into a line-switching component (for CS1, CS2) and a packet-switching component (for PS1, PS2, PS3). The line-switching component operates using synchronous time-division multiplexing. In each case, for example, 70 packets, each comprising 40 octets, are combined on each input line to form a frame. Without special measures, this would produce delays in each switching stage of the order of 40 x 70 x 8 bits = 22,400 bits; for each input of a switching stage 22,400 bits of memory space would be required. 
<??>According to the invention, all packets are divided in the exchange into packet parts of equal length and distributed among sub-frames. Switching is carried out on the basis of sub-frames. Delays and memory space requirements are reduced by the frame : sub-frame ratio. 
<??>Fixed positions are preferably allocated to the higher-priority connections (CS1, CS2) in each frame and each sub-frame for the entire duration of the connection. 
<??>Packet parts of the remaining packets are preferably arranged in sequence in remaining free positions and re-combined within each switching stage to form complete packets.

Patent PT-83497-B (PT)
IPC: B24B19/22
Filed: 1986-10-07
Abstract: By means of the process, workpieces are guided to sharpening machines, the workpieces being fed in the direction of advance for subsequent machining by means of an advancing element 1, a press-on part 2 and a lateral stop 5. For the automatic feed in the correct position, a continuous rotational movement is imparted to the workpiece 3 during the advance, in such a way that, during the advance, it is pressed constantly against the stop 5. The guide device has a gap 39 for leading the workpiece 3 through, the said gap being formed by the rotatably driven advancing element 1 and the opposite press-on part 5. The gap 39 is limited laterally by the stop 5 and has an at least approximately constant height irrespective of the position of the cutter 33 of a knife 4. The axis of rotation 40 of the advancing element 1 is at an acute angle  gamma <''> to a plane 46 containing the cutting edge 53 of the knife 4. During the passage of the workpiece 3, the advancing element 1 always generates a run-on force which is directed towards the stop 5 and by means of which the workpiece 3 is always pressed against the stop 5. As a result, the workpiece 3 runs in exact alignment onto the following knife which can consequently sharpen the edge of the workpiece 3 accurately (Figure 4). <IMAGE>

Abstract: The preparation of pharmaceutical powder compositions which are directly compressible into tablets, is disclosed. The disclosed process includes subjecting an aqueous slurry/solution of a pharmaceutically active drug specifically naproxen or naproxen sodium (which slurry may be directly obtained without drying from the synthesis of the drug), alone or in admixture with an aqueous mixture of excipient materials, to a controlled form of spray drying to produce a dry powder of uniform particle size wherein the drug is uniformly dispersed in and coated with the excipients. The powder can be readily combined with additional dry excipient materials and formed into tablets. The process provides for substantial savings in the manufacture of the tablets. The spray dried powder compositions are highly compressible. Utilizing such spray dried powder compositions, the tablets formed are readily dissolvable and also are stable under normal storage conditions and stress conditions of temperature and relative humidity.
